Data acquisition and automation with LabJack
With this video course, you will learn how to use the
LabJack device to perform data acquisition and control (DaQ) operations.
This course is ideal if you want to reliably record a lot of data from sensors so that you can analyze it later or control the environment in real-time.
The LabJack is a robust data acquisition device that is used in factories, warehouses, buildings, labs, and homes.
Think of LabJack as a PLC (industrial Programmable Logic Device), but at a lower price point and easier to learn and use.
For example, you may want to record the volume of water that flows through a pipe, the temperature of a fridge, or the movement of a high-rise building due to winds. And, you may want to do this for ten years without any human intervention.
This course is also ideal if you want to control the environment based on the data collected from sensors.
For example, you may want to adjust the pressure in a water pipe using a variable valve if the pressure sensor shows it is above a certain threshold. Or, you may want to raise an alarm if the temperature of a fridge rises above 0°C.
Who is this course for?
LabJack is a tool for data acquisition and control.
LabJack was designed to be robust and reliable, to work autonomously in harsh environments for a long period of time, and to have a lot of input/output ports able to connect to a huge range of sensors and actuators.
What are the objectives of the course?
LabJack can be used via an intuitive graphical user interface, and is programmable using any one of the many mainstream programming languages.
You can start taking measurements without writing a single line of code.
You can also write simple or complex scripts that run both on the device or on a host computer to automate data acquisition and control through a network.
What are the knowledge prerequisites?
